Chip700r Posted April 27, 2013 Report Posted April 27, 2013 So in the process of applying more power to my bike via porting, I decided that I would have my cylinders honed to deglaze them. After putting the top end back together and kicking it over it creates a clattering noise. Like the piston is moving back and forth in the cylinder. The bike had a noise similar to this but now it's considerably louder. Any tips would be much appreciated. Quote

Chip700r Posted April 27, 2013 Author Report Posted April 27, 2013 Yeah that's what I feared I'm pulling the head off again Tomorow Quote
CAJUN BANSHEE Posted April 27, 2013 Report Posted April 27, 2013 At least you didn't try and pull start it. Seems to be a trend lately. Quote
bansheesandrider Posted April 27, 2013 Report Posted April 27, 2013 Did you check your rods while it was apart? Is your crank welded? When your crank spreads and the rod bearings go away they make a clattering noise. Quote
Chip700r Posted April 27, 2013 Author Report Posted April 27, 2013 Yeah I figured it out. When he honed the cylinders he took them out a bit too far. The cylinders literally just meet the max wear limit. That said we've decided to rebore it and get new pistons $$$. So any recommendations on a .75 over piston. Quote
tdod101 Posted April 27, 2013 Report Posted April 27, 2013 At least you didn't try and pull start it. Seems to be a trend lately. Pull start like a lawn mower or pull start like towing it and dropping the clutch Quote

Not sure if they make them for banshees but I've had good luck with SPI T-Molly series pistons. Put them in my sled bored .010 over. Very pleased Quote
oldskool Posted April 27, 2013 Report Posted April 27, 2013 Are you going from a 64 mm bore(stock) to a 64.75? You really want to go as small as possible and save cylinders for future bores. Maybe your cylinders need this much to clean up. IDK. Wiseco has 64.0mm, 64.25mm, 64.50mm,64.75mm, 65.00mm and so on Quote
Nieskes Posted April 28, 2013 Report Posted April 28, 2013 Pull start like a lawn mower or pull start like towing it and dropping the clutch lol!!!!!! Quote
CAJUN BANSHEE Posted April 28, 2013 Report Posted April 28, 2013 lol!!!!!! Rope around the flywheel works every time haha Quote
Chip700r Posted May 31, 2013 Author Report Posted May 31, 2013 Hey fellas just giving an update. Managed to get a newish set of cylinders and a head then bored it to 65. Was running great in dunes then a sudden sputter and it quit. I'd put up a photo but I don't know how basically my right piston has a pretty serious hole in it now. So 700$ for three tanks worth of running is pretty good right?..right?? Quote
